NLSX5014 4-Bit 100 Mb/s Configurable Dual-Supply Level Translator The NLSX5014 is a 4-bit configurable dual-supply autosensing bidirectional level translator that does not require a direction control pin. The I/O VCC- and I/O VL-ports are designed to track two different power supply rails, VCC and VL respectively. Both the VCC and the VL supply rails are configurable from 0.9 V to 4.5 V. This allows a logic signal on the VL side to be translated to either a higher or a lower logic signal voltage on the VCC side, and vice-versa. The NLSX5014 offers the feature that the values of the VCC and VL supplies are independent. Design flexibility is maximized because VL can be set to a value either greater than or less than the VCC supply. In contrast, the majority of competitive auto sense translators have a restriction that the value of the VL supply must be equal to less than (VCC - 0.4) V. The NLSX5014 has high output current capability, which allows the translator to drive high capacitive loads such as most high frequency EMI filters. Another feature of the NLSX5014 is that each I/O_VLn and I/O_VCCn channel can function as either an input or an output. An Output Enable (EN) input is available to reduce the power consumption. The EN pin can be used to disable both I/O ports by putting them in 3-state which significantly reduces the supply current from both VCC and VL. The EN signal is referenced to the VL supply.

Timing Definitions for Propagation Delays and Enable/Disable Measurement http://onsemi.com 10 HIGH IMPEDANCE NLSX5014 IMPORTANT APPLICATIONS INFORMATION Level Translator Architecture VL pins to a high impedance state. Normal translation operation occurs when the EN pin is equal to a logic high signal. The EN pin is referenced to the VL supply and has Over−Voltage Tolerant (OVT) protection. The NLSX5014 auto−sense translator provides bi−directional logic voltage level shifting to transfer data in multiple supply voltage systems. These level translators have two supply voltages, VL and VCC, which set the logic levels on the input and output sides of the translator. When used to transfer data from the I/O VL to the I/O VCC ports, input signals referenced to the VL supply are translated to output signals with a logic level matched to VCC. In a similar manner, the I/O VCC to I/O VL translation shifts input signals with a logic level compatible to VCC to an output signal matched to VL. The NLSX5014 translator consists of bi−directional channels that independently determine the direction of the data flow without requiring a directional pin. One−shot circuits are used to detect the rising or falling input signals. In addition, the one−shots decrease the rise and fall times of the output signal for high−to−low and low−to−high transitions. Uni−Directional versus Bi−Directional Translation The NLSX5014 translator can function as a non−inverting uni−directional translator. One advantage of using the translator as a uni−directional device is that each I/O pin can be configured as either an input or output. The configurable input or output feature is especially useful in applications such as SPI that use multiple uni−directional I/O lines to send data to and from a device. The flexible I/O port of the auto sense translator simplifies the trace connections on the PCB. Power Supply Guidelines The values of the VL and VCC supplies can be set to anywhere between 0.9 and 4.5 V. Design flexibility is maximized because VL may be either greater than or less than the VCC supply. In contrast, the majority of the competitive auto sense translators has a restriction that the value of the VL supply must be equal to less than (VCC − 0.4) V. The sequencing of the power supplies will not damage the device during power−up operation. In addition, the I/O VCC and I/O VL pins are in the high impedance state if either supply voltage is equal to 0 V. For optimal performance, 0.01 to 0.1 mF decoupling capacitors should be used on the VL and VCC power supply pins. Ceramic capacitors are a good design choice to filter and bypass any noise signals on the voltage lines to the ground plane of the PCB. The noise immunity will be maximized by placing the capacitors as close as possible to the supply and ground pins, along with minimizing the PCB connection traces. The NLSX5014 translators have a power down feature that provides design flexibility. The output ports are disabled when either power supply is off (VL or VCC = 0 V). This feature causes all of the I/O pins to be in the power saving high impedance state. Input Driver Requirements Auto−sense translators such as the NLSX5014 have a wide bandwidth, but a relatively small DC output current rating. The high bandwidth of the bi−directional I/O circuit is used to quickly transform from an input to an output driver and vice versa. The I/O ports have a modest DC current output specification so that the output driver can be over driven when data is sent in the opposite direction. For proper operation, the input driver to the auto−sense translator should be capable of driving 2 mA of peak output current. The bi−directional configuration of the translator results in both input stages being active for a very short time period. Although the peak current from the input signal circuit is relatively large, the average current is small and consistent with a standard CMOS input stage. Enable Input (EN) The NLSX5014 translator has an Enable pin (EN) that provides tri−state operation at the I/O pins. Driving the Enable pin to a low logic level minimizes the power consumption of the device and drives the I/O VCC and I/O http://onsemi.com 11 NLSX5014 PACKAGE DIMENSIONS UQFN12 1.7x2.0, 0.4P CASE 523AE−01 ISSUE A ÏÏ ÏÏ ÏÏ D PIN 1 REFERENCE 2X 0.10 C 2X 0.10 C NOTES: 1.
